CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 686,827', dated November 14, 1899.

Application led June 14, 1899. Serial No. '720,5 82. (No model.)

.To all whom it may concern:

Be it known that l, BRUNO MILCH, a subject of the King of Prussia, German Emperor, residing at No. 29 Burgstrasse, Berlin, in the Kingdom of Prussia, German Empire, have invented certain newl and useful Improvements in Car-Oouplin gs, of which the following is a specification.

This invention refers to a car-coupling in which the two parts effecting the coupling proper are made to engage one with the other by the impact occurring on moving one car (railway-'car or street-car or the like) against the other, the engagement of the parts being automatically fixed by certain arrangements and combinations of parts, as described hereinafter.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the different views, and in which- Figure l is a side View of the coupling, partly in section. Fig. 2 is a section in line A B of Fig. l. Fig. 3 shows the coupling parts proper when out of engagement. Fig. 4 shows a part of the bar that carries one-half of the coupling, (not shown in this figure.) Fig. 5 is a front view of the connection between the aforementioned bar and the respective half of the coupling, and Fig. 6 shows a slightly-modified form of construction of the left-hand end of Fig. l.

The coupling parts proper consist each of a disk i, Figs. l, 2,and 3, having diagonallylocated hook-like projections lo, that are bent out of the plane of the disk and serve for connecting two disks with each other, as is shown in Figs. l and 2. One disk fila belongs, ofcourse, to the coupling of one cargand the other disk belongs to the coupling of the other car. The disk/L is secured to a longitudinally-displaceable bar h, Figs. 1, 4, and 5, passing through a sleeve d. The connection between that disk and the bar h is effected by a bolt Z, Fig. 5, the arrangement being such that the disk c' may move in a horizontal plane, as is made necessary in curves and by other lateral movements of the car. To constantly bring the disk i back into normal position after each deviation, the bar h is surrounded by a sleeve fm, having a disk fn, and a spring o is inserted between this disk and a collar p, Fig. l, of

The sleeve d is located in a collar c of a cyl-l inder b and is provided with lateral ledges e, preventing the sleeve from turning in the cover, but allowing a longitudinal displacement of the same. The sleeve d is further provided with a collar g, against which presses one end of a spring f, inclosed in the cylinder b. The strength of the spring f is greater than that of the spring o, and the bar h will thus be displaced in the sleeve d when an impact between two cars takes place. The sleeve d and the bar h are connected by a pin r, projecting forth from said bar and taking into an inclined slot q, provided in said sleeve. When an impact between two cars occurs, and when consequently the bar h is displaced in the sleeve d, the pin r is of course displaced in the slot q, and in consequence of the inclination of that slot the bar h is turned in the sleeve d, so that the disk c', with its hook-like projections k, is rotated for a certain extent.- Owing to this rotation, which takes place at the couplings of the cars, the coupling parts proper-z'. e., the hooks c--engage with each other; but as soon as such en= gagement is completed the bar h is fixed in the position it then has received by a slide Fig. l, taking into a longitudinal slot s, Fig. 4, of said bar. This slot gets in line with the slide t only when the bar h has sufficiently been rotated by the influence of the inclined slot q upon the pin r; but also after this engagea ment of the slide in the slot s the bar h may f nrther be displaced in its longitudinal direction in case the impact between the two cars should have been so strong as to displace also the sleeve d in the cover c, when also the spring j' will be correspondingly compressed. The cylinder b is secured to a plate a, secured in its turn to the respective car.

The sleeve m, with the disk n in the spring o, may be dispensed with if the cylinder b is arranged so as to be able to swing in a horiroo zontal plane. In the formbf construction shown in Fig. 6 the cylinder b is furnished with projections it and the plate ct is furnished with projections and these parts are connected with each other by bolts v, so that the cylinder b may swing around said bolts.

The slide t may be connected with an ad jacent device showing whether or not the parts i 7o are in proper connection with the respective parts of the adjacent coupling.

Having now described the nature of my said invention, what I desire to secure by Letters Patent of the United States is- 1. In a car-coupling the combination with a rotary disk having coupling-hooks, of a spring-seated longitudinally-displaceable bar to which said disk is secured, a non-rotatable sleeve embracing said bar and having an oblique slot in its side, a pin from said bar entering said slot to cause the bar to rotate as it yields and thereby move the coupling-hooks into engagement, and a bolt arranged to be dropped into a lengthwise slot in said bar upon the completion of such rotation and hold the parts in engaged position.

2. In a car-coupling the combination with a disk t having coupling-hooks 7o, of a longitudinally-displaceable bar h having said disk attached to it, a longitudinally-displaceable sleeve d embracing said bar, ledges c preventing said sleeve against turning, means for guiding said sleeve, an inclined slot q provided in the latter, a pin 1* fixed to the bar taking into the slot, another slot s provided in the said bar, a bolt i adapted to take into said slot s and a springf tending to move the sleeve d in the direction to the coupling-disk i 7o, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
